DEVICE FOR SHARPENING HORSESHOE-CALKS.

SPECIFICATION forming part of Letters Patent No. 600,734, dated March15, 1898.

Application filed my 15, 1897.

To aZZ whom it may concern:

Be it known that I, JAMES LANG MARTIN, of Marion Centre, in the countyof Indiana and State of Pennsylvania, have invented a new and ImprovedDevice for Sharpening Horseshoe-Oalks, of which the following is a full,clear, and exact description.

The object of the invention is to provide a machine simple, durable, andeconomic in its construction whereby the calks of a horseshoe may berestored to their proper shape or sharpened Without removing the shoefrom the hoof.

The invention consists in the novel construction and combination of theseveral parts, as will be hereinafter fully set forth, and pointed outin the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in both figures.

Figure 1 is a vertical section through the machine, and Fig. 2 is atransverse vertical section taken centrally.

The body-frame A of the machine is horizontally sustained and comprisesa bottom 10, in which a central opening 11 is made, sides 12, ends 13,and flanges 14, which are projected horizontally from the end portionsinwardly over the bottom, being connected With the sides. The body-frameA is supported at its ends upon legs 15, and a single central leg 16 ispreferably provided at one side of the said body-frame. Twoshaping-levers 17 and 18 are pivoted or j ournaled at their inner endsin the end portions of the body-frame. The inner end portions of theseshaping-levers are brought in close relation, and when the said leversare in their normal position they will have an upward inclination attheir inner end portions, said inner ends bearing against each other attheir lower portions, the said portions being rounded or given more orless of a cylindrical shape.

The inner ends or shaping portions of the lovers are designated as 18,and when these levers are in their normal position a wedgeshaped space19 is afforded between the aforesaid shaping edges, as shown in Fig. 1.An operating-lever 20 is fulcrumed in a support 21, attached to thesingle leg 16, or said lever 20 may be otherwise fulcrumed. A link 22$erial No. 644,610. (No model.)

is pivotally connected with the inner or shaping end of the lever 17,and a parallel link 23 is correspondingly connected with the oppo siteshaping-lever 18, the two links being carried downward to the lever 20,which may be operated by hand, and are pivoted to said lever, one ateach side, ordinarily through the medium of a single pivot-pin.

The shaping-levers being in their upper or normal position, if, forexample, the toe-calk of the horseshoe is to be sharpened or reshapedwhile the shoe remains on the hoof of the animal, the said calk isintroduced into the space 19 between the shaping-surfaces of the twolevers 17and 18, as shown in Fig. 1, it being simply necessary to raisethe hoof carrying the shoe. By pressing downward on the lever 20 the twoshaping-levers will be drawn downward and their shaping-surfacesengaging with opposite sides of the calk will roll or press the calk ina manner to elongate the same, and thereby impart to it the necessarytapering shape, terminating in a pointed or sharp lower end.

The device is exceedingly simple, yet it is practical and effective inoperation.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. In a machine for shaping horseshoe-oalks, thecombination, with a frame and an operating-lever, of shaping-leverspivoted at opposite sides in the said frame, the inner surfaces of theshaping-levers being shaping-surfaces, the lower portions of theshaping-surfaces having rounded contour, the said surfaces being alsoheld in engagement, the upper portions of the shaping-surfaces normallydiverging, forming between them a substantially wedge-shaped space, andlink connections between the shaping-levers and the op-* crating-lever,for the purpose specified.

2. The combination with a frame, of two shaping-levers bearing againstthe frame at their outer ends and having their inner ends engaged witheach other, a link connected with the inner portion of eachshaping-lever, and an operating-lever bearing on the frame below theshaping-levers and having connection with the links whereby to drawdownward the inner ends of the shaping-levers.

3. The combination of a horizontally-elongated frame havingvertically-extending sides ing-lever, and an operating-lever bearing onand an orificed bottom run between the sides, the frame and connectedwith the links whereof two shaping-levers, the outer ends of which by todraw downward said links.

bear on opposite sides of the frame, and the JAMES LANG MARTIN. innerends of which are engaged and located Witnesses:

adjacent to the opening in the bottom, a link J. H. MOGINITY,

connected with the inner portion of each shap- HUGH M. BELL.
